2014-09-10Object: Add support for bigobjDavid Majnemer1-9/+2
This adds support for reading the "bigobj" variant of COFF produced by cl's /bigobj and mingw's -mbig-obj. The most significant difference that bigobj brings is more than 2**16 sections to COFF. bigobj brings a few interesting differences with it: - It doesn't have a Characteristics field in the file header. - It doesn't have a SizeOfOptionalHeader field in the file header (it's only used in executable files). - Auxiliary symbol records have the same width as a symbol table entry. Since symbol table entries are bigger, so are auxiliary symbol records. Write support will come soon. Differential Revision: http://reviews.llvm.org/D5259 llvm-svn: 217496

2014-03-04llvm-objdump: Indent unwind info contents.Rui Ueyama1-11/+11
Unwind info contents were indented at the same level as function table contents. That's a bit confusing because the unwind info is pointed by function table. In other places we usually increment indentation depth by one when dereferncing a pointer. This patch also removes extraneous newlines between function tables. llvm-svn: 202879

2014-03-04llvm-objdump: Print x64 unwind info in executable.Rui Ueyama1-4/+33
The original code does not work correctly on executable files because the code is written in such a way that only object files are assumed to be given to llvm-objdump. Contents of RuntimeFunction are different between executables and objects. In executables, fields in RuntimeFunction have actual addresses to unwind info structures. On the other hand, in object files, the fields have zero value, but instead there are relocations pointing to the fields, so that Linker will fill them at link-time. So, when we are reading an object file, we need to use relocation info to find the location of unwind info. When executable, we should just look at the values in RuntimeFunction. llvm-svn: 202785

2014-02-28llvm-objdump: Fix crash bug with printing unwind info on stripped file.Rui Ueyama1-7/+9
The current COFF unwind printer tries to print SEH handler function names, assuming that it can always find function names in string table. It crashes if file being read has no symbol table (i.e. executable). With this patch, llvm-objdump prints SEH handler's RVA if there's no symbol table entry for that RVA. llvm-svn: 202466

2014-02-20llvm-objdump/COFF: Print SEH table addresses.Rui Ueyama1-0/+22
SEH table addresses are VA in COFF file. In this patch we convert VA to RVA before printing it, because dumpbin prints them as RVAs. llvm-svn: 201760
2014-02-19llvm-objdump/COFF: Print load configuration table.Rui Ueyama1-0/+41
Load Configuration Table may contain a pointer to SEH table. This patch is to print the offset to the table. Printing SEH table contents is a TODO. The layout of Layout Configuration Table is described in Microsoft PE/COFF Object File Format Spec, but the table's offset/size descriptions seems to be totally wrong, at least in revision 8.3 of the spec. I believe the table in this patch is the correct one. llvm-svn: 201638

2014-01-30Simplify the handling of iterators in ObjectFile.Rafael Espindola1-18/+5
None of the object file formats reported error on iterator increment. In retrospect, that is not too surprising: no object format stores symbols or sections in a linked list or other structure that requires chasing pointers. As a consequence, all error checking can be done on begin() and end(). This reduces the text segment of bin/llvm-readobj in my machine from 521233 to 518526 bytes. llvm-svn: 200442

2014-01-16llmv-objdump/COFF: Print export table contents.Rui Ueyama1-1/+33
This patch adds the capability to dump export table contents. An example output is this: Export Table: Ordinal RVA Name 5 0x2008 exportfn1 6 0x2010 exportfn2 By adding this feature to llvm-objdump, we will be able to use it to check export table contents in LLD's tests. Currently we are doing binary comparison in the tests, which is fragile and not readable to humans. llvm-svn: 199358
2014-01-15llvm-objdump: Don't print "Import table:" header if there's no import table.Rui Ueyama1-3/+5
If a binary does not depend on any DLL, it does not contain import table at all. Printing the section title without contents looks wrong, so we shouldn't print it in that case. llvm-svn: 199340

2013-09-27llvm-objdump: Dump COFF import table if -private-headers option is given.Rui Ueyama1-0/+46
This is a patch to add capability to llvm-objdump to dump COFF Import Table entries, so that we can write tests for LLD checking Import Table contents. llvm-objdump did not print anything but just file name if the format is COFF and -private-headers option is given. This is a patch adds capability for dumping DLL Import Table, which is specific to the COFF format. In this patch I defined a new iterator to iterate over import table entries. Also added a few functions to COFFObjectFile.cpp to access fields of the entry. Differential Revision: http://llvm-reviews.chandlerc.com/D1719 llvm-svn: 191472
